# nix-store-add-fixed(1)

add paths to store using given hashing algorithm

## Name

`nix-store --add-fixed` - add paths to store using given hashing algorithm

### Synopsis

`nix-store` `--add-fixed` \[`--recursive`\] *algorithm* *paths…*

### Description

The operation `--add-fixed` adds the specified paths to the Nix store. Unlike `--add` paths are registered using the specified hashing algorithm, resulting in the same output path as a fixed-output derivation. This can be used for sources that are not available from a public url or broke since the download expression was written.

This operation has the following options:

- •

  `--recursive`

-

  Use recursive instead of flat hashing mode, used when adding directories to the store.

-

  *paths* that refer to symlinks are not dereferenced, but added to the store as symlinks with the same target.
